Q
A

Exarate pupae:

  1. Appendages are free and not glued to the body, usually without cocoon, but often a cell made from dirt or debris.
  2. Present in all holometabolous orders, but only in primitive Lepidoptera.
  3. In higher Diptera (house flies), exarate pupa is enclosed within the last larval instar skin (forming a puparium or coarctate pupa)
